1. This represents the difference between the number of stock appreciation rights ("SARs") exercised (25,000) and the number of shares issued as a result of the exercise (4,598). Each SAR represents the right, upon exercise, to receive a number of shares of Class A Common Stock equal in value to the number, if any, by which the 10-calendar day volume-weighted average price of the Company's Class A Common stock prior to the exercise date exceeds the exercise price.

2. This represents the withholding of shares of Class A Common Stock to satisfy tax withholding obligations associated with the exercise of the SARs reported in this Form 4.
